MATLAB: cannot call or index into a temporary array [duplicate]

Question

I am trying to read data files each containing one column and 4097 rows. But my function needs total numbers of rows with even number (means 4096). So I used the MATLAB command x(2:length(x))). But my 'x' value in this command is a(:,k) and the issue is MATLAB cannot call or index into a temporary array. Any solution to this? I thank all for the support. The code is:

for k = 1:9
with filename = sprintf('F00%d.txt',k);
a(:,k) = load(filename);
x = a(:,k)(2:length(a(:,k)));
w = tqwt(p,1,3,3);
[a1,a2,a3,a4]= deal(w{:});

 m(a1,1) = mean(a1);
 s(a1,1) = std(a1);
 ma(a1,1) = max(a1);
 mi(a1,1) = min(a1);

Unfortunately, you have to split x = a(:,k)(2:length(a(:,k))); into two lines as shown below:

temp = a(:,k);
x = temp(2:length(a(:,k)));
